The top 10-15 rails see helpers, should I learn first?

Question

I study rails 3 and want to know which vision assistants I should master first?

i.e. which ones are most commonly used?

1. form_for 2. ?? .. .. 

Answer 1

I think that they are generally considered very important, and they should give you a good start to understand the code and create your own forms and pages.

• form_for
• link_to
• IMAGE_TAG
• stylesheet_link_tag
• javascript_include_tag
• content_for
• label_tag
• text_field_tag
• submit_tag
• select_tag
• options_for_select
• check_box_tag
• radio_button_tag
• form_tag
• collection_select

Some other useful ones:

• auto_link
• plural
• simple_format

I would also work on understanding the difference between just calling select_tag and calling f.select, where f is the form_for variable. These are usually two different ways to create forms with helpers in Rails.

I would also like to make sure that you understand the html_safe, raw and h functions for strings and display the text on your page.

If you have not already done so, read the tutorial here:
